Huang Fuxian killed prince Li Ling without informing the emperor and hence was deposed by the emperor. This kind of behavior was stupid. Even though Li Ling was evil , after all he was a son of the emperor, you had no right to execute the emperor’s son without even notification in advance. By the way, never kill a person in haste, after all, which is a thing about life and death. Kin is important too. Just like Mao Renfeng dared to oppose Jiang Jingguo and used all kinds of method to try to persuade Jiang Jieshi to punish his own son. He was muddle-headed, because Jiang Jingguo was Jiang Jieshi’s son, thus Mao himself died miserably. Not only think thrice before you speak, but also before you do.
